GYRATING CRUSHER.

SPECIFICATION formingpart of letters Patent No. 525,443, dated September 4, 1894.

Application filed November 3, 1893- Serial No. 489,945. (No model.)

To all whom it may concern:

Be it known that we, CHARLES L. CARMAN, ELMER E. HANNA, and PHILETUS WARREN GATEs, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Gyrating' Crushers, of which the following is a specification.

In the drawings, Figure '1 is a vertical longitudinal section through our improved crusher; Fig. 2 a plan view of the crusher;

and Fig. 3 a plan View of a section taken in line 3 of Fig. 1.

In making our improved crusher for crushing ores, rocks, and othersubstances, we make a shell, A, which we will term the upper shell. This shell terminates at the top in a lateral flange,'a, provided with a vertical outer rim, a, and at the lower end in an outwardly flarmg flange, a This shell is what may be termed. a split shell. In casting, it is provided with a slit, a through from one end to the other. It is provided with lateral lugs, A, on each side of the split, through which horizontal bolts, a may be passed, so that the shell may be drawn together by screwing on the nuts of the bolts. In finishing the shell, we draw it together to the desired extent, bore out the interior as much as desired, and then loosen the bolts to permit the shell to spring out and resume its original position. We make a lining, B, which forms the crushmg surface, and which is intended to be arranged within the upper shell. In casting, this lining or crushing surface is preferably provided on its outer surface with a number of vertical strips, b, of soft metal, which protrude somewhat beyond the surface. This facilitates the finishing of the lining to the proper size, as of course it is easier to finish the soft metalistrips than the hard casting. After the lining or crushing surface has been finished, it is inserted in the shell, A, and the bolts, a screwed up so as to securely clamp the shell upon the lining. The bottom of the lining may be even' with the bottom of the shell, and is intended to rest upon the removable ring, I), arranged at the bottom of the upper shell and at the top of the lower shell hereinafter described, which ring, however, we may say need not be an entire circle, but may be made in segments if desired. We arrange a spider, C, at the top of the upper shell, provided with a circumferential flange, 0, extending downwardly and resting on the top of the lining or crushing surface, so that it will hold the same down securely in the desired position when the parts are fastened together. The spider is also provided with a downwardly inclined circumferential flange, C, that overhangs, butpreferably does not rest upon, the top of the upper shell. As shown in the drawings, the space, 0 is left between them.

In order to fasten the spider and the upper shell securely together and hold the spider in its proper position, we arrange a ring, D, provided with an inclined surface on its inner side adapted to rest upon the inclined surface of the spider, as shown in Fig. 1, so that the two surfaces may be wedged or dovetailed together. We provide this ring with the desired number of holes, and pass bolts, (1, through it and through the lateral flange, a, of the upper shell, and tighten them with nuts until the ring, D, has been drawn down and the spider, C, secured with the desired degree of tightness. While we prefer that the ring, D, shall be an entire circle, yet we mean by the term ring to cover it whether made in one or several parts. i We make a lower shell, E, which'is provided at its upper end with a shoulder, e, on which the ring, b, is intended to rest, and with a circumferential inwardly inclined flange, c. This shell is also split for a portion of its length from the top down, and it is provided with lugs, 8 on the respective I gether by the bolts, 6 so as to securely fasten them inplace. The flanges; a and e, are made segmental, with spaces, e in them, as shown in Fig.3. These spaces are intended to be equal'to the length of the Segments, so that the segmental flanges, a may beinserted in the segmental-spaces, efl'and thenthe shell turned around untiltheyv fit into 'the flanges, e, as shown in Fig. 1, when the bolts are tightened and the parts fastened together, as above explained. We also-provide an inclined, removable diaphragm, F, for carrying off the crushed material.

The lower shell isprovided with-an opening, closedby a plate, G, which is provided with a horizontal bearing in which is arranged a shaft, G, carrying a pulley, G ,so-

that it may be rotated by the application of any convenient motive power. A pinion, g, isarranged on the inner end of the-shaft so as" to rotate with it,and-its teeth are intended to engage or mesh with the teeth of a gear, g removablyattached or connected to an cecentricbox, H,but so that the two will ro- The pinion,vg, andgear, g,

shown inFig, 1.- Thisportion'may,however,

if preferred; be madeas-aseparate' diaphragm and afterward inserted.

The portion of the shell surrounding; the shaft,.H',.is provided-with two upwardlyextending; flanges, h, which atford an annular channel or space between them, which may: be filled with water or oil, and which iscoveredby a cap, it, provided with downwardly extending flanges, .h one of which extends:

down into the water or oil with which the channel; between the flanges, h, isintended to: be filled. This makes or afiordsafluid seal to prevent dust, dirt, or other'foreign substances from getting into: the" eccentric box or gearing. Of course, it-will' be understood that the cover, h, is attached to the shaft, H,.and moves and is covered andprotected by a water lip, H ,v fastened to the shaft and overhanging the top of thecap, h. The -shell is provided" with: a:- removable-bottom, I, which maybe removably. secured to the shell in: any desired manner. When it is in place, there is formed between itandt'he part, gala chamber inwhich the: actuating mechanism operates,yand-which may be filled wit-h oilto act as a lubricantgas will be readily' understood from an: inspection of Fig. 1.
